If I have a form panel which contains say employee name , last name and salary and tax based on that salary.
Initially I will show all elements except tax .
When users fill up all the details and after saving , at server end I will calculate tax and will come back on same form showing all fields as readable along with tax field.
1. initially DOM should not contain tax field but later on it should... How can I do that ?
2. How can I show those fields as readable only ..
