First up im not code savy which is why i went with a plugin
my theme is bricks
the end goal is to have a my users create a budget list
1. the 'hide from front end' doesn't hide the block.. it completely disables it which means its not capturing the required meta. i have got around this with my own css display:none... but it kind of defeats the purpose of having a 'hide from front end' option that doesnot submit fields with default meta
2.after submitting a custom field MB frontend form that is set to 'save in database', its creating a new post and not saving in the database. However it does save in the database when i select 'create new table' but that resets all my table settings to text
3. the shortcode [rwmb_meta id="category_name" storage_type="custom_table" table="hd_budget_category"] is not working
2, 3. The custom table created automatically in the builder uses data type TEXT for all columns to be compatible with most fields. Can you please share some screenshots of the field category_name and field group settings? Where do you add the shortcode on your site?
