Hi Francus,
By default, Joomla's textarea type uses a safe filtering mode that removes most HTML for security reasons.
You can update your XML file to include the filter attribute on the relevant textarea fields, there are 2 values you can consider:
filter="safehtml" to permit common safe HTML tags (including <b>, <strong>, <em>, <p>, <br>, lists, and basic tables) while still providing some protection against malicious code
filter="raw" if you need unrestricted HTML (e.g., scripts or arbitrary tags) -- but this is less secure and not recommended unless necessary.
For example, you want to allow these HTML tags: <b>, <strong> tags for the Answers of the Questions field:
1/ Open file: [root]/templates/ja_vega/etc/extrafields/services-info.xml
2/ Look for this field and add the filter attribute as below:
<field
name="question_desc"
type="textarea"
label="TPL_SERVICES_QUESTION_DESC_LABEL"
description="TPL_SERVICES_QUESTION_DESC_DESC"
filter="safehtml"
/>
Hope this helps.
