I have two quantities Cat A , CatB
Now the items in Cat A can belong to many items in CatB.
and CatB will also have many Items from Cat A.
I thinking of having Table1 for Cat A , Table2 for CatB and Table C for relation ship.
with
PK-A , PK-B
Is that correct.
How should i make my form in html so that user can select multiple values.
Currently i am using select box
Any ideas?
Yes, in a relational database, a relationship table with foreign key into the two tables being related many-to-many is indeed the right way to go.
In HTML, use
<select multiple="multiple">for a multiple-selectionselect.It would be best to ask these two separate questions as two separate questions, btw!-)
