When you insert Custom Filters in Toolset Views you can decide whether to apply "Fully styled output" (It uses Bootstrap) or "Raw output" (it will output a minimal HTML so you can customize it more freely).
With fully styled output the single Checkboxes are wrapped in a DIV, and usually, you will not put several DIV's inline.
Hence I suggest using the "Raw output" when inserting the Filter as a set of checkboxes.
If you do that, the checkboxes will become an unordered list.
This can then easily be modified by CSS as outlined here in this "tutorial": hidden link
