I meed some help and am new to Xoops.
I am running Xoops 2.5.1a (http://www.hawkeyemed.com/xoops) and have MyTabs 2.21 and MyMenus 1.1 installed.

I have created a menu using MyMenus which is working fine with static pages that I devleop using fmContents. I know how to link that fmContents pages on MyMenus.

The issue I am having is knowing how to invoke a MyTabs Block from MyMenus. I created a multi-tab Menu Manager in MyTabs and have created a Block in MyMenus. Now I want to display this block ONLY if a particular Menu item in MyMenus is selected. Currently the block has a property "visible:no" so the block is hidden.

What do I set in "Link" property of the Menu item to display the block?

To be honest, I don't know how to do it. You might look into another great module by Trabis: "BlocksAnywhere" - maybe this will help?

If I remember correctly, the "Designing for XOOPS" book is also covening "blocks anywhere" in themes.
