jcgonzalezmartin 

Because i want following 2 options
1.Multiple grid option
for e.g.

Invoice Billing register

Fields :  Place, organization , date , voucher no (single fileds)
Multiple fields : Item name , Qty,Rate, Amt

I need multiple grid option to enter item used in bill

2. I want category and subcategory hierarchy
if i selection country dropdown then its related state will come in next dropdown, again after selection of state its city will come in next dropdown & so no.

i want this 2 feature which are not available in sharepoint online so can you please suggest me how can i achieve this
