A Combobox is a composite widget that lets a user select one or more optons, from a predefined or autocompleted searchable list. The result of that selection is then shown as the value of an input, inside the Combobox widget.

The multi-select Combobox can have more than one selected option. When more than one option has been selected, the value of the input should be updated with the total number of selected items, such as "3 options selected".

When a Combobox with multiple selected options is closed, a listbox of pills is also used to represent those selected options. The listbox of pills is positioned below the read-only input, each pill represents a selected option. This allows a user to easily see and remove selected items from the Combobox. The Combobox comes with 2 distinct variations of functionality. A "Read-Only and an "Autocomplete" Combobox. A read-only Combobox allows a user to select an option from a pre-defined list of options.

It does not allow free form user input, nor does it allow the user to modify the selected value. An autocomplete Combobox also allows a user to select an option from a list but, that list can be affected by what the user types into the input of the Combobox. This can be useful when the list of options a user can choose from is very large, as user input can start to only display options that match the text the user has entered, effectively performing a search. If no option matches, the user can complete the value of the combobox by finishing their own text entry.

The listbox of options can be displayed as just a simple single list, or that list can be grouped with headings, to better organise the options. The target HTML element, slds-combobox and dropdown need to be wrapped in the class.

A space-separated list of element IDs that provide labels for the combobox. By default the list is aligned with the selection field at the top left so the list opens down.

Use bottom-left to make the selection field display at the bottom so the list opens above it. Use auto to let the component determine where to open the list based on space available.Only one list item is displayed at one time in a ComboBox and other available items are loaded in a drop down list.

Only one list item is displayed at one time in a ComboBox and rest of the available items are loaded in a drop down list. Creating a ComboBox control at run-time includes creating an instance of ComboBox class, set its properties and add ComboBox instance to the Form controls. First step to create a dynamic ComboBox is to create an instance of ComboBox class.

The following code snippet creates a ComboBox control object. The following code snippet sets location, width, height, background color, foreground color, Text, Name, and Font properties of a ComboBox. To do so, we use Form. Add method. The following code snippet adds a ComboBox control to the current Form. The easiest way to set properties is from the Properties Window. You can open Properties window by pressing F4 or right click on a control and select Properties menu item.

The Properties window looks like Figure 2. It is used to access control in the code. The following code snippet sets and gets the name and text of a ComboBox control. When you click on the Collections, the String Collection Editor window will pop up where you can type strings.

Each line added to this collection will become a ComboBox item. I add four items as you can see from Figure 6. View All. Mahesh Chand Updated date, Mar 07 The ComboBox control provides combined functionality of a text box and a listbox in a single control. Once a ComboBox is on the Form, you can move it around and resize it and set its properties and events using the Properties and Events windows. Once the ComboBox control is ready with its properties, the next step is to add the ComboBox to a Form.

Setting ComboBox Properties Alternatively, you can set control properites at design time. The Location property is a type of Point that specifies the starting position of the ComboBox on a Form. You may also use Left and Top properties to specify the location of a control from the left top corner of the Form. The Size property specifies the size of the control. We can also use Width and Height property instead of Size property.

The DropDownHeight and DropDownWidth properties represent the height and width of the dropdown area in pixel respectively. If all the items do not fit in the size of the dropdown area, the scrollbars will appear as you can see from Figure 3.

In your javascript controller, you can get the component using the find method and then get the attribute value of the comonent using the get method.

Refer this Trailhead module for more details. In your code snippet you are using hybrid controls instead of aura controls. When you do that the get "v. You can use javascript to reference the html element but it might be better to use the ui:inputSelect and ui:inputSelectOption controls. Also if you are using hybrid controls you might want to check out this example: Events with Client-side controllers. Lightning Design System is CSS only framework and there you can find out only html markup examples and not the javascript pieces how to manipulates the data.

Instead of implementing your own component for simple select list it's better to use a standard on lightning:select. A lightning:select component creates an HTML select element. This component uses HTML option elements to create options in the dropdown list, enabling you to select a single option from the list. Multiple selection is currently not supported.

And regarding to getting values in js controller and passing it to APEX the basic approach is the following:. I do not understand guys why everybody trying to get selected value by select aura:id. In theory you can make a typo and get value of other select. For me safer and the only proper way to get value of select list is obtain it from event, like below.

Use below Code snippet in Component 1. Mark Pond By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Salesforce Stack Exchange is a question and answer site for Salesforce administrators, implementation experts, developers and anybody in-between.

It only takes a minute to sign up. Hello I am trying to create a autocomplete using lighting components, The first attempt was to use the lightning:combobox but this doesn't allow me to use the input box such as input of type search. I am able to use some of the documentation from the lighting design system, but I am unable to set the focus to the 1st index of the listitem in my aura:iteration.

It would be great to just use the lightning:combobox instead of using all of the markup from the lightningdesignsystem. One thing to mention is I don't get the options when the page loads I don't receive any options for the filteredOptions attribute until i type 2 characters into the input. Depending on the search result length, the final rendered HTML markup will have many div elements with id value as option1. Per HTML standards, the id attribute should always be unique unless you have a valid use case in your application.

So, the lightning platform is most likely confused about finding a single element to focus on due to multiple elements with same ID attribute value. CreateComponent to dynamically construct and render the search results, but I do not recommend it as it will cause really bad performance in this case.

Also, since dynamic attributes cannot be specified for the ID attribute via expressions in lightning and the search results will always vary, I think you could get rid of the aria attribute and the div ID attribute unless you are using them for something else in the component. You could try using tabindex and element. In the JS file, use the following code note that this is only a pseudo-code and you might have to modify it.

Please note that I've not tested this code in lightning framework, but have used similar code in other JS frameworks in the past. Another possible solution would be create a custom component instead of using aura:iteration and that way you would be able to pass appropriate values on the ID attribute. As far as the options and filteredOptions values go, you might want to post the JS code in the question for further troubleshooting.
