Focus (<b:focus />)

<b:focus> allows you to define the field that gets the input focus when the page is loaded.

Basic usage

Simply add <b:focus target="someId" > somewhere in your JSF page. The input field bearing this id gets the input focus. The attribute target may also contain a search expression, as long as it results in a unique id.

Some input fields allow you to activate the focus even simpler, by putting <b:focus> inside the input field:

In this example, the focus doesn't seem to work for two reasons: there's a second demo below, which overrides the focus of the first demo, and after that you've clicked the tab, which focuses the tab instead of the input field. However, in a simple form <b:focus /> works as described.

Search expressions

<b:focus /> also works with search expressions. This may allow you to get rid of the ids.
