Best is to avoid booleans altogether. Use a text field with yes or no. This means not using the toggle component also, and use icons with custom visibility instead.
Hello,
the problem is that when Adalo updates a record, it sends all the fields to Xano and if a field has no value or is false, Xano receives that info and updates the value in the table.
To solve this Xano has 2 filters that can be used to tell Xano that if the value received is null or empty, to put the old value of that field, this way the values are not deleted.
For non-boolean fields you can use first_notempty and for boolean fields you can use first_notnull.
