How can I customize form to let me choose multi industries instead of once at a time !
You need to add a Multiselect field (custom) https://docs.erpnext.com/docs/user/manual/en/customize-erpnext/articles/table-multiselect-field
However, this will not reflect in the existing standard Reports
Thanks so much ! That worked !
Can I ask you one more question ? I have create 2 select form which named Service Group and Service Detail, which should I look at if I want to customize them like I have many groups of services and I have to choose the service group first then the erp will load corresponding service detail in Service Detail form.
For example : I have service groups A & B. Each group contains service detail C & D ( correspond to group A ), E & F ( correspond to group B ). If I choose service group A in Service Group form, it will load only service detail C & D in Service detail form.
