For the dropdown, its a know issue that you have buttons In buttons, still need to fix that one. For the colors, looks like your bootstap3 template is missing some css, what you can try is to load the default bootstrap3 css file before, and check which classes are missing.
For the reply issue, I will check if I got the same issue, but for now is will fix fatals issues first, when I fixed those issues, if will do the css fixes.
I also have several error like:
- quick reply opens the form but on bottom and i´m not able to scroll down to send.
This is with a bootstrap js error with "empty string getElementByID -> FIXED switching to Modal View
- Second the answer form has no icons, no toolbar. -> also FIXED switching Icons
Also with another template...
