If a popup/context menu is assigned to a target component via the popup/context attribute, the popup will show up when the user clicks on the target component.

If the popup has not shown up yet, clicking the target component will cause the popup to show up. If the popup is showing up, clicking on the target component again will toggle the popup to hide.

Popup

Employment/Purpose

The popup is a container that does not have any special frame. You can associate a popup with any component by specifying the popup's id at one of the following attributes: 

    <button popup="popup_id"/>
    <button tooltip="popup_id"/>
    <button context="popup_id"/>

    <popup id="popup_id">
        this is a popup
    </popup>

Example

ZKComRef Popup.PNG 

<separator bar="true" />
<label value="Tooptip for Another Popup" tooltip="any" />
<popup id="any" width="300px">
	<vbox>
		ZK simply rich.
		<toolbarbutton label="ZK your killer Web application now!"

<popup id="popup" width="300px">
	<vbox>

		<toolbarbutton label="ZK your killer Web application now!"
			href="http://www.zkoss.org" />
	</vbox>
</popup>

Position

You can simply specify a popup's position when attaching to a component by

  • built-in position
  • x, y coordinate
<button popup="popup_id, position=overlap_end"/>
<button popup="popup_id, x=50,y=50"/>


Since 6.0.1 ZK supports the following position string:

ZKComRef Popup Position 601.png

overlap, overlap_end, overlap_before, overlap_after are kept (still available) for backward compatibility. They are identical with top_left, top_right, bottom_left, and bottom_right, respectively. 

Before 6.0.0

The 14 possible positions are provided below:

ZKComRef Popup Position.png

The following illustrates the simplicity of usage, 

<popup id="pp">
	Here is popup
</popup>
<button label="before_start" onClick='pp.open(self, "before_start");' />

Upon clicking the button the popup component will appear in the relative position specified. In this case the position is just above the button.

Methods

Toggle Popup

Since 7.0.0 If a popup/context menu is assigned to a target component via the popup/context attribute, the popup will show up when the user clicks on the target component. Click the target component again, the popup will still show up by default. As of 7.0.0, The popup/context attribute supports an additional toggle type, which could make the target component act as a toggle switcher. If the popup has not shown up yet, clicking the target component will cause the popup to show up. If the popup is showing up, clicking on the target component again will toggle the popup to hide. The usage is in the below code. 

<button label="Popup" popup="id, type=toggle"/>

Tooltip Delay

The tooltip attribute can also support a delay, the following code outlines how to accomplish this. 

<label value="Tooltip" tooltip="popup_id, position=before_start, delay=500"/>
