I would recommend you enter a date picker (https://docs.webix.com/api__refs__ui.datepicker.html). That would take parameters like invalidMessage and you could create a single custom rule that uses a Regular Expression to evaluate the date. It also makes the user's job easier for data entry.
I wanna view single invalidation message , if i didn't fill date or month or year in a column i.e common validation message for dob column ,
please take look at this url => https://snippet.webix.com/h3158pfc
and my date must be garter than 0 less than 32 , month must not empty,and year must be greater than 1900 . and also i just wanna see invalidMessage not as webix.Message().
This is my actual form ==> https://snippet.webix.com/gbblsip7
