Disable add button in touch ui multifield

Hi,

You need to write code to achieve that e.g.

AEM - Touch UI Component Dialog Field Regex/Custom Validation

You can write this code on event of Add button

$inputEle = $("your multifield item")

var multiFieldItem = $inputEle.find("coral-multifield-item").size();

var multiFieldbutton = $inputEle.find(".coral-Button")

                if (multiFieldItem > max) {

                // disabled add button using javascript

multiFieldbutton.attr("disabled", "disabled");

                }
