To start, sorry for my rough English but I speak French.
I would like to create a new application with, on the right of the map, a toolbar that would contain several widgets.
Then I would like the content of each widget to open in another div.
I followed this discussion but I can't seem to position the widgets vertically and make their content visible in another div.
Attached is a view of the application design

Thank you in advance for the help you can give me.
Ps: i'm webdesigner but new in javascript.
