Hello,

I also stumbled into a similar problem. Manually inserting a non-breaking space ( ) between the fields did not work - even when using its Unicode value.

I ended up using an 'invisible comma' (⁣).

eg. <field name="some field"/>&#x2063;<field name="some other field"/>

Really i was asking for a line seperator between two fields because i have two sets of field and i want to make a line space betwwen the two fields : i do that by adding new field called space :

in .py file :

'space': fields.char(' ', readonly=True)

in .xml file :

<field name="space"/> 

the result is empty line space.

add empty div with heigth tag between gruops.it will give space between to groups.
<div style="height:50px">
</div>
