How to create poplist LOV based on condition in WEBADI

I have a requirement wherein, when some value is selected from existing table LOV only then poplist lov should appear for other values selected from table lov it should not be shown,

For Example:

1) at header level parameter_1 is attached with std table Lov in which there are 100 records,

2)Among those 100 values when the value ''ABC" is selected the poplist should appear in another column. If other than "ABC" is selected poplist should not appear.

3) column called "NAME_VALUE" should be attached with poplist LOV based on the above validation.

Can anyone help me with this? Thank you in advance.
