Content properties​

These properties are customizable options present in the property pane of the widget, allowing users to modify the widget according to their preferences.

Label​

Text string​

Sets the label on the widget.

Position string​

Allows you to choose the placement of the label. You can choose:
  • Left - Aligns the text to the left of the Switch.
  • Right - Aligns the text to the right of the Switch.

Alignment string​

Alignment refers to how a label is positioned relative to a widget. By adjusting this property, you can bring the label closer to the switch within the widget's layout.

General​

Default State boolean​

Determines whether the Switch is initially set to on or off.

Visible boolean​

Controls the visibility of the widget. If you turn off this property, the widget would not be visible in View Mode. Additionally, you can use JavaScript by clicking on JS next to the Visible property to conditionally control the widget's visibility.

For example, if you want to make the widget visible only when the user selects Yes from a Select widget, you can use the following JavaScript expression: 

{{Select1.selectedOptionValue === "Yes"}}

Disabled boolean​

Prevents users from selecting the widget. Even though the widget remains visible, user input is not permitted. Additionally, you can use JavaScript by clicking on JS next to the Disabled property to control the widget's disable state conditionally.

For example, if you want to allow only a specific user to fill the input, you can use the following JavaScript expression: 

{{appsmith.user.email=="john@appsmith.com"?false:true}}

Animate Loading boolean​

This property controls whether the widget is displayed with a loading animation. When enabled, the widget shows a skeletal animation during the loading process. Additionally, you can control it through JavaScript by clicking on the JS next to the property.

Height string​

This property determines how the widget's height adjusts to changes in its content. There are three available options:

  • Fixed: Maintains a constant height for the widget, allowing you to adjust it by dragging or using the resize handle.
  • Auto Height: The widget's height adjusts dynamically in response to changes in its content.
  • Auto Height with limits: Same as Auto height, with a configurable option to set the minimum and maximum number of rows the widget can occupy.

Events​

onChange​

Allows you to define a set of actions that would be executed in response to the switch state change.

Style properties​

Style properties allow you to change the look and feel of the widget.

Font color string​

Represents the text color of the widget, specified as a CSS color value. It can also be manipulated programmatically using the JavaScript functions.

Font size string​

Determines the font size of the label. It accepts CSS font-size values and can also be programmatically modified using JavaScript functions.

Emphasis string​

Enables you to select a font style for the widget, such as bold or italic. Additionally, the font style can be programmatically modified using JavaScript functions

Accent color string​

The accent color property specifies the color used to highlight the switch when it is turned on. It accepts CSS color values and can also be programmatically modified using JavaScript functions.

Reference properties​

These properties are not available in the property pane, but can be accessed using the dot operator in other widgets or JavaScript functions. For instance, to get the visibility status, you can use Switch1.isVisible.

isSwitchedOn boolean​

The isSwitchedOn property retrieves a boolean value that indicates whether the switch is turned on. It returns true if the switch is on and false if it is off.

Example:

{{Switch1.isSwitchedOn}}

isDisabled boolean​

The isDisabled property reflects the state of the widget's Disabled setting. It is represented by a boolean value, where true indicates that the widget is not available, and false indicates that it is enabled for user interaction.

Example:

{{Switch1.isDisabled}}

isVisible boolean​

The isVisible property indicates the visibility state of a widget, with true indicating it is visible and false indicating it is hidden.

Example:

{{Switch1.isVisible}}

Methods​

Widget property setters enable you to modify the values of widget properties at runtime, eliminating the need to manually update properties in the editor.

These methods are asynchronous and return a Promise. You can use the .then() block to ensure execution and sequencing of subsequent lines of code in Appsmith.

setVisibility (param: boolean): Promise​

Sets the visibility of the widget.

Example:

Switch1.setVisibility(true)

setDisabled (param: boolean): Promise​

Sets the disabled state of the widget.

Example:

Switch1.setDisabled(false)

setRequired (param: boolean): Promise​

Sets whether the widget is required or not.

Example:

Switch1.setRequired(true)

setValue (param: boolean): Promise​

Sets the value to be displayed in the widget.

Example:

Switch1.setValue(true)

setColor (param: string): Promise​

Sets the background color of the widget.

Example:

Switch1.setColor('#FF0000')
