Adding an Gallery+ block is the same process as adding any block in Headway. The Gallery+ block will appear in the list of available blocks under the “More Blocks” block selection menu.
This will create an empty Gallery+ block that you can then set to configuring to your heart’s desire.
Once you add a Gallery+ block, the first thing you need to do is open its options and choose the gallery type..
Then Save, and reload the page. When you open the options for the block now,, it will show those of the gallery type you selected.
