Add scroll bar on Multi Line Text

[Jaeik Lee]

Hi.

I am looking for the way to fix height of Multi Line Text in catalog item.

Best plan is show scroll bar when over the limit.

At least i make Multi Line Text stop expanding.

Thank you for help.

Hi @Jaeik Lee ,

ServiceNow will auto-expand all textarea until the height reaches 435px as defined in the CSS.

The auto-expand behavior is on the "input" event handler.

Not sure if it's the right way, but I made a simple UI script to change max-height, like the following:

EDIT: I missed the second parameter in the insertRule() function in the screenshot, without the second parameter, it won't work in some browsers, e.g. Firefox.

document.styleSheets[0].insertRule("HTML[data-doctype=true] textarea { max-height: 100px !important; }", 0);

Already tried that. but it didn't work.

@Jaeik Lee use max_length attribute to limit the length.

Refer: https://docs.servicenow.com/bundle/tokyo-servicenow-platform/page/product/service-catalog-management... 

Adding scroll bar using client script may or may not  be possible, if possible it will be a DOM which is not recommended by servicenow. The max_length attribute will restrict it from expanding

Applicable variables: Single-line text, Wide single-line text

I think it doesn't work
