Override Max Length on single line text variable

[Cirrus]

Afternoon, is anyone able to confirm if this can be done please. When building a catalog item, is it possible to set a maximum length value on a single line text variable unique to that variable?

I cant change the current dictionary value because of the following warning: The field 'Question' on table 'Question' contains existing data records (3593) that exceed the new length

I did find one post that suggested this could be done by an on load client script, but I havent got it to work, tried question.question_text and current.variables.variable_name

function onLoad() {
setTimeout(function() {
jQuery('input[name="current.variables.variable_name"').attr("maxlength","10");
}, 1000);
}

Hello @Cirrus 

Greetings!

you can add variable attribute max_length=200

refer the below article:

Ravi, I may be being a little stupid here, but the article says:

1. Navigate to the variable of single-line text or wide single line-text on the platform
2. Open the Default Value tab
3. Add the variable in Variables of single-line text or wide single line-text
   For example: max_length=150

What does line 3 actually mean? If I navigate to a single line text variable and put max_value=10 in the default value tab, it does just that, sets the default value of the field, not its length.

Also, is there a way to count characters in the portal. I know there is a system property in the UI.

Hello @Cirrus 

the article is little misguiding I'm afraid.

it's not the default value of the variable,

it is the default value of variable attribute. refer the below pic.
