In PocketBlocks, Drawer is an overlay sidebar to display information or perform operations, without interrupting the workflow on the main window.
The following example builds a shopping cart using a drawer.
When inserted by drag-and-drop operation, a Drawer floats on the right side (by default) of the main window. Then, you can add components onto the Drawer according to your needs. In the editing mode of a Drawer, other components on the canvas are not editable.
When a drawer is closed, you can re-open it by clicking the corresponding label in the Modals tab in the left pane.
In the Properties tab, you can set the position of the drawer. The default position is the right side of the main window.
In Properties tab, you can set the width of the drawer by pixels or percentage. Note that the height of a drawer is the same as the main window and is not customizable.
You can reference a drawer in JS code anywhere in your app or call it through a "control component" action in Properties > Interaction > Event handlers.
The following sections guide you through how to open and close a drawer by clicking a button in an online shopping app.
Usually, in an app, you trigger opening a drawer by an event such as clicking a button. For example, opening a drawer to display the shopping cart is implemented in the following steps.
Add a button and rename it as gotoCart.
Set the event handler of the button. Select "Control component" as the Action and select the component "cart" and method "openDrawer". All these settings are auto-saved.
Click the button gotoCart and the binded drawer "cart" is open.
Triggerring "closeDrawer" is similar to triggering "openDrawer". When setting up the event handler, select the method "closeDrawer". For example, closing a drawer that displays the shopping cart is implemented in the following steps.
Add a button and rename it as gobackShopping.
Set the event handler of the button. Select "Control component" as the Action and select the component "cart" and method "closeDrawer". All these settings are auto-saved.
Click the "Continue Shopping" button and the binded drawer "cart" is closed.
