React

activeStateEnabled

Specifies whether the UI component changes its visual state as a result of user interaction.

Type:

Boolean

Default Value: false

The UI component switches to the active state when users press down the primary mouse button. When this property is set to true, the CSS rules for the active state apply. You can change these rules to customize the component.

Use this property when you display the component on a platform whose guidelines include the active state change for UI components.

animationDuration

Specifies the duration of the drawer's opening and closing animation (in milliseconds). Applies only if animationEnabled is true.

Type:

Number

Default Value: 400

animationEnabled

Specifies whether to use an opening and closing animation.

Type:

Boolean

Default Value: true

See Also

closeOnOutsideClick

Specifies whether to close the drawer if a user clicks or taps the view area.

Type:

Boolean

Function

Function parameters:
event:

Event (jQuery or EventObject)

The raised event. It is a EventObject or a jQuery.Event when you use jQuery.

Return Value:

Boolean

true if the UI component should be closed; otherwise false.

Default Value: false

The function passed to this property enables you to specify a custom condition for UI component closing. For instance, you can prevent closing until a user clicks a specific element on the view:

jQuery
JavaScript
$(function() {
    $("#drawerContainer").dxDrawer({
        // ...
        closeOnOutsideClick: function(e) {
            return e.target === $("#someElement").get()[0];

opened

Specifies whether the drawer is opened.

Type:

Boolean

Default Value: false
Raised Events: onOptionChanged

See Also

openedStateMode

Specifies how the drawer interacts with the view in the opened state.

Type:

OpenedStateMode

Default Value: 'shrink'

The following modes are available:

  • "overlap"
    The drawer overlaps the view. If you assign "overlap" to the openedStateMode property, the Drawer uses the Popup component to render a side menu. A z-index of all overlay UI components (Popup, Popover, etc.) on a page is calculated when a component is created and it takes into account the z-indexes of existing overlays. As a result, a newly opened Popup (the Drawer's panel) is displayed at the top. If you need to display a different window at the top, call the focus() method for the Popup after the openedStateMode property is changed.

  • "shrink"
    The view's width decreases to accommodate the drawer.

  • "push"
    The drawer partially displaces the view.

Note that if the value of this property changes, the Drawer template is re-rendered.

position

Specifies the drawer's position in relation to the view.

Type:

PanelLocation

Default Value: 'left'

Use "before" and "after" if the Drawer should be positioned differently in right-to-left and regular representations. The following table shows the dependency between the rtlEnabled value and "before" and "after" positions:

"before" "after"
rtlEnabled: false left side of the view right side of the view
rtlEnabled: true right side of the view left side of the view

Top or Bottom Position Demo Left or Right Position Demo

revealMode

Specifies the drawer's reveal mode.

Type:

RevealMode

Default Value: 'slide'

The following modes are available:

  • "slide"
    The drawer slides in. The drawer and its content are animated.

  • "expand"
    The drawer expands from the closed position. The drawer's width is animated; its content is not.

When you change the Drawer's reveal mode, the component needs to perform recalculations for animation. As a result, the template is rerendered which can increase loading time.

View Demo

See Also

rtlEnabled

Switches the UI component to a right-to-left representation.

Type:

Boolean

Default Value: false

When this property is set to true, the UI component text flows from right to left, and the layout of elements is reversed. To switch the entire application/site to the right-to-left representation, assign true to the rtlEnabled field of the object passed to the DevExpress.config(config) method.

JavaScript
DevExpress.config({
    rtlEnabled: true
});

shading

Specifies whether to shade the view when the drawer is opened.

Type:

Boolean

Default Value: false

template

Specifies the drawer's content.

Type:

template

Template Data: undefined
Default Name: 'panel'

DevExtreme HTML5 JavaScript Drawer

This property specifies the drawer's content. To specify the view's content, nest it inside the Drawer's markup element as shown in the code below.

IMPORTANT
Always specify a fixed width for the drawer's content because this is used to calculate the drawer's width. If the drawer is positioned on the y-axis, specify a fixed height for the drawer's content because it determines the drawer's height.
jQuery
index.js
$(function() {
    $("#drawerContainer").dxDrawer({
        template: function() {
            const $drawerContent = $("<div>").width(200);
            // ...
            // Specify the drawer's content here
            // ...
