How to group channels together?
 

I'd like to group all of my channels together. Right now they each have a separate green header bar... but I want them all together under one green bar. I can only seem to make sub-forums:

I want it to look like this:

Could be 2 causes it looks like this.

Your style have that bar between every channel or you managed your channels "wrong".

Please give us a link to look into your code or take a screenshot of your adminpc - channel manager and post it here.

Yes that greenbar maybe is category bar. The forums should be put under one category,

1. if none category exist you need to create one. Make sure when creating the category under Admincp> Add new forum> Posting> Act as Channel> NO - pick NO so that it will be a category, And the dont touch the parent level - when creating new it will be on top level under Forum

Then put all those 3 forums under the parent of the one category you have created. To do this you need to edit all 3 forums one by one,

2. Admincp> Channel manager> forum name> edit channel> under channel, parent channel > pick the parent category

3. And make sure Admincp> Channel manager> forum name> edit channel> Posting> Act as Channel> Yes -- for each forums so that it wont be a category.
