Java Development Tools

hi,

1) How can we align the 'save' , 'search', 'reset' buttons in af:query component to left?( without using skin)

2)I want to control operators appearing for multi-select LOV appearing in advanced mode .
Though i am able to remove some of the operators using <comp oper , TODO =-2/> , i was unable to remove 'Less than', 'Greater than', 'Less than or equal to', 'Greater than or equal to'

How can i remove these operators?

and i was able to remove operators for only attributes mentioned in criteria.

3) IS there a way in which i can control operators for the attributes added through 'Add Fields' in advanced mode of Af:Query
