I have requested this earlier occasion too
I see that now you have changed the work experience time period looks like label
if we use views accordion for work experience this can be implemented in very simple way without custom coding in fact one can use any field as label using views accordion
there is another advantage of views accordion module
the list of experiences can be very long and resume will look awkward with scroll bar
only work experiences are changed(edited) normally.if you can implement views accordion only for the work experience field collection it will be good .
Could you please consider this request
