‌Select / Dropdown widget is used to capture user input/s from a specified list of permitted inputs.

How to use Select Widget

Displaying data

A Dropdown's options can be populated from a data source like an API / Query by transforming the incoming data to an array of (label, value). The transformation can be performed using JavaScript. So if the data is an array, it can be transformed using the function.

// is assumed to be an array here
{{ => {
return { label:, value: }

Filtering data

A Dropdown can be used to filter a dataset based on the user's input. The selected value can be passed to an API using**{{ dropdownName.selectedOptionValue }} .

Form submission

Dropdown widgets can be used to capture from a fixed set of options inside a form such as gender, role, and status.


Some forms need to be pre-filled data from a table or API. You can bind the data to the default text property to enable this

{{ Table1.selectedRow.gender }}
* Binding this to the default option will update the selected option
* of the dropdown with the gender of the selected row in Table1

Widget properties

These properties allow editing the Select widget. All these properties are present in the property pane of the widget.

OptionsUse to set labels and values for different items/options in the list of the dropdown widget. Options must be specified as an array of objects with a label and value property.
Default ValueSets a default option that's captured as user input unless it's changed by the user.

Server Side FilteringEnables server-side filtering via an API / Query request. Use this property when the Select widget's Option data is being bound to an API / Query.

Binding properties

These properties help to share values between widgets and also allow easy access to the widget property within Queries or JS functions.

filterTextThe filter text for Server side filtering{{widget_name.filterText}}
isDisabledThis property indicates whether the widget is disabled or not.{{widget_name.isDisabled}}
isVisibleThis property indicates whether the widget is visible or not.{{widget_name.isVisible}}
selectedOptionValueThis is the value of the option that's displayed in a Single Select dropdown. It changes if the default value of the dropdown changes or the user selects an option{{widget_name.selectedOptionValue}}
selectedOptionLabelThis property indicates label of the selected option.{{widget_name.selectedOptionLabel}}


These are functions that are called when event listeners are triggered in the widget.

onOptionChangeSets the action to be run when the user selects/unselects an option. See a list of supported actions.


The property hosts a group of configurations that are used to associate a display name and define a placement for the widget. Below are the properties that affect Labels:

TextSets the label of the widget.
PositionSets the label position of the widget.
AlignmentSets the label alignment of the widget.
WidthSets the label width of the widget as the number of columns.

Here are the label properties in detail:


Sets the display name for the Select widget. Users see this name on the page with the widget, like a title.


Leaving the field empty sets the widget to have no display name.


It allows specifying the placement of the label. You can select one of the available options:

  • Top - Aligns the text at the top of the Select widget.
  • Left - It aligns the text to the left of the Select widget. When the Left alignment is selected, there are additional settings that can be used to control the alignment and define the text's width.
    • Alignment - Controls the placement of text relative to the Select widget. The options are:
      • Left - Aligns the text to the widget's left boundary that's away from the Select widget.
      • Right - Aligns the text closer to the Select widget.
    • Width - Sets how much space is allocated to the label, measured in number of columns of the canvas grid.
  • Auto - Automatically adjusts the position of the text based on the Select widget's height.

Columns are the dashed lines (-----) that surround a widget when it's being placed on the canvas.

How to set the label properties?


Style properties allow for customizing the look and feel of the widget.

Label Text ColorSets text color for the label.
Label Text SizeSets the size of the label.
Label Font StyleSets the font style, such as bold or italic.
Border RadiusSets the rounded-ness of the widget's corners.
Box ShadowSets the widget's shadow style.

Server-side filtering

The Select widget has the option to configure server-side filtering, where search queries are sent to the back-end, and responses are used to populate options on the Select widget. When enabling server-side filtering in the widget, please update the default value to contain both label and value in this format {"label":<label>, "value": <value>} if the default value isn't present in the default options.

Server Side Filtering

As shown in the Server Side Filtering video, follow these steps:

  1. Drag a Select widget onto the canvas.
  2. Create a query get_users that retrieves user data to use in the widget. For example, try working with Appsmith's users Postgresql test database. Use the following statement as the query:
    SELECT id, name FROM users ORDER BY id LIMIT 10;
  3. In the Select widget's properties pane, add the query's data to the widget's Options property. To control how the returned data is structured, use the JS map() method:
    {{ user => {
    return { label:, value: }
  4. Enable the Select widget's Server Side Filtering property, and set the onFilterUpdate event to execute the query.
    {{ }}
  5. Now that the widget is configured for server side filtering, update the get_users query with a WHERE statement that incorporates the filter text from the Select widget:
    SELECT id, name FROM users
    WHERE name LIKE '{{'%'+ Select1.filterText + '%'}}'
    ORDER BY id LIMIT 10;

In the Select widget's filter field, enter text to narrow the query's results.
