I want to take a field (in this case the Description field from a Case) and make it into a Lightning Component so I can add it to the right hand side of my layout view with related lists.. How would I write this? Or if you have a better idea I'm all ears.
Are you using "Related list - multiple"? If I read you correctly, if you have the action that allows you to see the description you want in a "tile", then instead try dragging a "Tab" (basically a blank tile to put stuff) over to the right pane and embedding multiple "Related list - Single"s of what you want from the related lists. You have more control over what is inside a "tab" than you would a "related list - multiple" item. Then drag over your new lightning component with the description in between any of the related singlets you have and I believe it should look right. I don't have time at the moment to check if what I'm saying would work, but I'll give it a look tomorrow when I'm back at it. Sorry if it sounds confusing.
Before:
"Related List - Multiple"
After:
"Tab"
"Description" component
"Related List - Single"
"Related List - Single"
"Related List - Single"
