"Inspect" a hover element?

Question

Note: I've read similar threads, but none quite my issue - I can right click on it fine, it just then disappears.

I find "Inspect Element" an invaluable tool in Chrome, however my latest foray as I learn the wizardly ways many of you already possess saw me creating a sub-menu for an element on my nav bar, which pops up below on hover of it's parent item.

The popup(or down) isn't quite styled how I'd like, so I right-click > inspect element to see what's coming from where exactly, and get a better idea of how to achieve my desired effect.

However, as soon as I move my mouse away from the menu, it's gone.

So I can't select different elements in the inspection pane, and see which area is highlighted at the same time.

Is there a way around this, without changing the menu so that it stays "popped up" once activated?

Answer 1

If the hover is triggered by JS, just pause script execution via the keyboard. This is a much simpler way of freezing the DOM than the other answers suggest.

Here's how you do it in Chrome. I'm sure Firefox has an equivalent procedure:

1. Open up Developer Tools and go to Sources.

2. Note the shortcut to pause script execution—F8.

   

3. Interact with the UI to get the element to appear.

4. Hit F8.
5. Now you can move your mouse around, inspect the DOM, whatever. The element will stay there.

If the hover effect is given with CSS then yes, I normally use two options to get this:

One, to see the hover effect when the mouse leave the hover area:
Open the inspector in docked window and increase the width until reach your HTML element, then right click and the popup menu must be over the inspector zone... then when you move the mouse over the inspector view, the hover effect keep activated in the document.

Two, to keep the hover effect even if the mouse is not over the HTML element, open the inspector, go to Styles TAB and click in the upper right icon that says Toggle Element State...(dotted rectangle with an arrow) There you can manually activate the Hover Event (among others) with the checkbox provided.

If it's not clear at all, let me know and I can add a few screenshots. Edited: screenshot added.

And finally and as I say at the begining, I only be able to do this if the hover is set with CSS:HOVER... when you control the hover state with jQuery.onMouseOver for example, only works (sometimes), the method One.

Hope it helps.
