Drawer
Sometimes, Dialog does not always satisfy our requirements, let's say you have a massive form, or you need space to display something like terms & conditions, Drawer has almost identical API with Dialog, but it introduces different user experience.
TIP
Since v-model is natively supported for all components, visible.sync has been deprecated, use v-model="visibilityBinding" to control the visibility of the current drawer.
Basic Usage
Callout a temporary drawer, from multiple direction
You must set model-value for Drawer like Dialog does to control the visibility of Drawer itself, it's boolean type. Drawer has three parts: title & body & footer, the title is a named slot, you can also set the title through attribute named title, default to an empty string, the body part is the main area of Drawer, which contains user defined content. When opening, Drawer expand itself from the right corner to left which size is 30% of the browser window by default. You can change that default behavior by setting direction and size attribute. This show case also demonstrated how to use the before-close API, check the Attribute section for more detail
No Title
When you no longer need a title, you can remove it from the drawer.
Set the withHeader attribute to false, you can remove the title from drawer, thus your drawer can have more space on screen. If you want to be accessible, make sure to set the title attribute.
Customized Content
Like Dialog, Drawer can be used to display a multitude of diverse interactions.
Customized Header
The header slot can be used to customize the area where the title is displayed. In order to maintain accessibility, use the title attribute in addition to using this slot, or use the titleId slot property to specify which element should be read out as the drawer title.
Resizable Drawer 2.11.0
Try to drag the edge part.
Set resizable to true to resize.
Nested Drawer
You can also have multiple layer of Drawer just like Dialog.
If you need multiple Drawer in different layer, you must set the append-to-body attribute to true
Modal
Setting modal to false will hide modal (overlay) of drawer.
Starting from version 2.11.6, modal-penetrable attribute is added, which can be penetrable.
TIP
The content inside Drawer should be lazy rendered, which means that the content inside Drawer will not impact the initial render performance, therefore any DOM operation should be performed through ref or after open event emitted.
TIP
Drawer provides an API called destroy-on-close, which is a flag variable that indicates should destroy the children content inside Drawer after Drawer was closed. You can use this API when you need your mounted life cycle to be called every time the Drawer opens.
