[IMP] web: consider select tag for o_row class

This commit will fix UI glitch when seletion field and
any other field kept on same line

Using o_row we can put two divs, two inputs side by side but
if we have case where from two elements 1 is input and second one
is selection widget then we will have glitches in UI,
this commit will fix that glitch
