You can make it by using the <ons-speed-dial>
element of Onsen UI: https://tutorial.onsen.io/?framework=vanilla&category=reference&module=speed-dial
If you want your buttons to be scattered like in the Debugger, then after choosing the direction of the <ons-speed-dial>
, add a margin to each of the <ons-speed-dial-item>
to place them where you want them to be.
