Why is 'custom' checkbox is checked by default while creating a new doctype

‘custom’ checkbox is checked by default while creating a new doctype, is it because developer mode is of ?
how to turn on developer mode?

Hi @Vinay1,

If a custom checkbox is checked then doctype will be stored in the database but not in the app.
If not checked then it will be stored in the app according to the module.

If you want to enable the feature then you should enable the developer mode.

I hope this helps.

Thank You!

You can activate developer mode using:

bench set-config -g developer_mode 1
