Hamburger (Bootstrap)

Description

Hamburger is a context dropdown, usually placed in the top right corner of a form. It usually contains commands and option settings for the user. Its name come from its appearance - a top and a bottom with a filling in the middle. It is virtually identical to the Dropdown (Bootstrap) control - it works the same way, but has different defaults.

When the control is created, selection is set to undefined.

Two onclick events happen when a Hamburger is clicked. When the control is initially clicked, an event is sent. When the user makes a selection, onclick is called again with the text of the selection.

To put a Hamburger on the left, set style to float:left; and align:left;

Popovers and Tooltips are supported.

When running on FireFox or IE, sometimes the Hamburger will disappear after being tapped. Add this to your onclick handler to bring it back:

setTimeout("Hamburger1.style.display = 'block'", 100)
