making the menu stay and not disappear on hovering out of the area
<p>Hi I have a header with a menu to its side, right now the menu gets displayed by dropping down once I hove on the arrow on the side of header and disappears once I move my cursor out of the menu dropdown area.</p>

<p>How do I make the menu stay until I click like the arrow button on the top again or have a button in the menu like 'ok' which will slide up the menu?</p>
