Invalid parameter "HTML Content": value is too long.

[Amosnomor]

First, thank you. This will be very useful.

I am running into a size limit trying to display several links:

<a href="https://zabbix.com target="_blank" rel="noopener noreferrer">First link</a>
<br>
<a href="https://zabbix.com target="_blank" rel="noopener noreferrer">Second link</a>
<br>
<a href="https://zabbix.com target="_blank" rel="noopener noreferrer">Third link</a>

Results in Invalid parameter "HTML Content": value is too long. when applying when editing the widget.

Reducing the size by removing the third link works:

<a href="https://zabbix.com target="_blank" rel="noopener noreferrer">First link</a>
<br>
<a href="https://zabbix.com target="_blank" rel="noopener noreferrer">Second link</a>

looks like up to version 6.4, the database field is type VARCHAR(255). That's why the content is limited to 255 characters.

The field was extended to 2048 characters in the current development branch of Zabbix. But it's hard to tell when and if this will be merged into the 6.4 branch.

I'll keep this issue open for now, maybe there is a workaround for this problem.
