[solved] New user question about how to create menus that look like this

Sorry to keep asking what I'm sure are simple questions but after playing around I just can't find the way to change this. About halfway through the video you set each item to "icon and text", and each icon displays the accompanying text in full ie "Internet Explorer". When I try this setting, the words are being cut off, for example it would show "Inter..."

How do I expand the width of each item to show the full text?

Thanks.
