The default for label alignment is left so that things look as follows:

However, you can change this to right so that the above becomes:

To change the label alignment you need to edit default.properties, located in <TOMCAT_HOME>/webapps/openvpms/WEB-INF/classes/style/default.properties- and having edited it (after first taking a backup copy) you need to restart Tomcat to get the changes to have effect.

Go to the section on Label alignment. i.e.:

 #
# Label alignment.
# This specifies the horizontal label alignment when:
# . editing and viewing objects
# . inputting report parameters
# Possible values are 'left' and 'right'
label.align = 'left'
  

and change 'left' to 'right'.

Note that it may be better to use the site over-ride facility - see Style - Site.
