Searchbox-example.png

<zscript>
ListModel model = new ListModelArray(new String[] {
  "North America", "South America", "Europe", "Asia", "Africa", "Oceania", "Antarctica"
});
</zscript>
<searchbox model="${model}" placeholder="An unknown place" autoclose="true">
   <template name="model">
       <html><![CDATA[
       <i class="z-icon-globe"></i> ${each}
       ]]></html>
   </template>
</searchbox>

Mouseless Entry Searchbox

  • UP or DOWN to pop up the list if being focused.
  • ESC to close the list.
  • UP, DOWN, HOME, END, PAGE UP and PAGE DOWN to change the selection of the item from the list.
  • ENTER to confirm the change of selection.

Properties

Autoclose

Sets whether to automatically close the list if a user selected any item. The default value is false. It means even if the user selected an item, the list still remains open. You might want to set it as true in single selection mode (multiple=false).

Disabled

Sets whether it is disabled. A list can still be opened programmatically by calling open() even if the component is in the disabled state.

ItemConverter

By implementing your own Converter, you can generate the label that represents the selected items. The default implementation is joining all the toString() result of items by commas.

ItemRenderer

See also: ZK_Developer's_Reference/MVC/View/Renderer/Searchbox_Renderer

By implementing your own ItemRenderer, you can generate the HTML fragment for the data model. Normally you would like to use the default implementation and use <template name="model"> instead.

Model

Since this component doesn't accept any child, you must specify a ListModel.

If a ListSubModel is provided, all the items will not be rendered to the client directly. Instead, users must type a keyword to search for a subset of the list. It's suitable for a large model.

Note: If you assign a ListModel to a searchbox, you should enable multiple selection with ListModel. Please do not set multiple on searchbox directly. You should set multiple on the model instead.

...
List Items = new ArrayList();
for (int i = 0; i < 1000; i++) {
	Items.add("data "+i);
}
ListModelList model = new ListModelList(Items);
model.setMultiple(true);
...

<searchbox model="${model}" ... />

Multiple

Sets whether multiple selections are allowed.

Open

Drops down or closes the list of items.

Placeholder

Sets the placeholder text that is displayed when there's nothing selected.

SearchMessage

Sets the placeholder message of the search text field. The default is "Type to search".

SelectedItem

Returns the selected item, or null if no item is selected. When multiple is true, it returns the first of the selected items.

Don't use MVVM annotations in both selectedItem and selectedItems at the same time since @save selectedItem will deselect all of the currently selected items first.

SelectedItems

Returns all selected items.
