DevExtreme Floating Action Button Enhancements (v19.2)

We added new functionality to the DevExtreme Floating Action Button: dxSpeedDialAction now supports label, visible and index options. The direction option is available for the floatingActionButtonConfig.

Action Labels

Specify the label option for the dxSpeedDialAction to display a text label next to an action button. The label is shown either in the Floating Action Button, or in the speed dial menu.

$(".action-add").dxSpeedDialAction({
  label: "Add to card",
  icon: "add",
  onClick:  function(e) { ... }
});

Action Visibility

We added the visible option to the dxSpeedDialAction to control item visibility. It is not necessary anymore to dispose and recreate the widget.

You can change the option after initialization to show or hide an action.

const addAction = $(".action-add").dxSpeedDialAction({
  icon: "add",
  visible: false,
  onClick: function(e) { ... }
}).dxSpeedDialAction("instance");

// later:
const newVisibility = ... // calculate visibility
addAction.option("visible", newVisibility);

Action Index

Set the index option to define the appearance order for actions in the speed dial menu. We implemented this option using the familiar logic of the CSS z-index: greater index values are farther away from the Floating Action Button.

$(".action-add").dxSpeedDialAction({
  icon: "add",
  index: 1,
  onClick: function(e) { ... }
});

$(".action-edit").dxSpeedDialAction({
  icon: "edit",
  index: 0,
  onClick: function(e) { ... }
});

Speed Dial Menu Direction

By default, the Floating Action Button is rendered in the bottom right corner of the browser window, and the speed dial menu expands upwards. We added the direction option to change the expansion direction of the speed dial menu. The default setting auto assigns the direction depending on the position configured for the Floating Action Button, but you can also use up or down to set the direction explicitly.

DevExpress.config({
  floatingActionButtonConfig: {
    position: {
      at: 'left top',
      my: 'left top',
      offset: '16 16'
    },
    direction: 'down'
  }
  // ...
});

Demo

We updated the Floating Action Button demo to illustrate the new options.
