<vue-draggable-resizable class-name-resizing="my-resizing-class">

classNameActive

Type: String

Default: active

Used to set the custom class of a draggable-resizable component when is active.

<vue-draggable-resizable class-name-active="my-active-class">

classNameHandle

Type: String
Required: false
Default: handle

Used to set the custom common class of each handle element. This way you can style each handle individually using the selector -, where handle code identifies one of the handles provided by the handle prop.

So for example, this component:

<vue-draggable-resizable class-name-handle="my-handle-class">vue-draggable-resizable>

renders the following:

<div ...>
  <div class="my-handle-class my-handle-class-tl">div>
  <div class="my-handle-class my-handle-class-tm">div>
  <div class="my-handle-class my-handle-class-tr">div>
  [...]
div>

disableUserSelect

Type: Boolean
Required: false
Default: true

By default, the component adds the style declaration 'user-select:none' to itself to prevent text selection during drag. You can disable this behaviour by setting this prop to false.

<vue-draggable-resizable :disable-user-select="false">

enableNativeDrag

Type: Boolean
Required: false
Default: false

By default, the browser's native drag and drop funcionality (usually used for images and some other elements) is disabled, as it may conflict with the one provided by the component. If you need, for whatever reason, to have this functionality back you can set this prop to true.

<vue-draggable-resizable :enable-native-drag="true">

active

Type: Boolean
Required: false
Default: false

Determines if the component should be active or not. The prop reacts to changes and also can be used with the syncmodifier to keep the state in sync with the parent. You can use along with the preventDeactivation prop in order to fully control the active behavior from outside the component.

<vue-draggable-resizable :active="true">

Styling

You can style the component using appropriate class names passed as props to the component. Moreover you can replace the default styles for the handles, provided in the source file vue-draggable-resizable.css, but you should take care to define position and size for them. The default classes for handles are handle and handle-tl, handle-br and so on.

The component also provides named slots for each handle, so you can use your markup inside each one.
