Maximum characters in help text

Hello Everyone.

I know that field level help text is allowed to 255 characters.

I would like to know what is the limit on the visualforce page?

Hi Sujit,

The limit remains same for the visual force page also.

You cannot increase the help text character limit but if you don't want to go for vf page then you can create a text area field, populate it with your help text, hide the field label and display it in a Read Only mode.

OR:

Use <apex:pageBlockSectionItem>, it has a helptext attribute that corresponds to the balloon. You can put your "long help" in a custom label for example so it can be translated to other languages like standard help texts.
<apex:pageBlockSectionItem helpText="Lorem ipsum ... (400+ chars)">
    <apex:outputLabel value="{!$ObjectType.Opportunity.fields.CurrencyIsoCode.Label}" />
    <apex:outputField value="{!Opportunity.CurrencyIsoCode}" />
</apex:pageBlockSectionItem>
User-added imageHope this helps.

Kindly mark this as solved if the information was helpful.

Thanks,
Nagendra
