I have tested this on Joomla 4.0.6. and I can't confirm this. You need to add URL schema (mailto:) to the field and email link is displayed correctly.

Although there are other issues, like mailto: schema displayed in email link.

Agree: If I add schema manually in front of email address, then email addresss (href) is build correctly but "mailto:" is visible in Frontend.

Since I select "mailto" from schema dropdown already, I would expect not to have to add it manually as well. And "mailto:" beeing visible in frontend is not good.

@idefax Its a multi-select box used to validate the type of link

@brianteeman But in the article, only one type of data will be entered into the field: either email, http URL, file etc. Why multi-select?
Besides this, adding schema "mailto:" as well in front of the email address might be no problem for experienced users, but it's not for not so experienced users. They would expect to enter email address only and link will be build corrrectly. My toughts.

And as mentioned in comments earlier: "mailto:" is visible in frontend.

Hey @idefax , could you elaborate a further more on how to reproduce this issue? I don't know if I did it correctly but I created a Url field and linked it with a valid email and it worked perfectly fine for me.

@Vanshitasingh

Step 1)
I open Articles > Fields. There I add a custom field of type "URL". In its settings I set parameter for schema to "Mailto":

Step 2)
After I edit an article and add email address into the new URL field. When saving, I get a warning message about missing schema, even if I have set it previously in step 1):

Step 3)
I add "mailto:" into email field:

Result:
Email link works in frontend, but schema is visible to user:

My thoughts:

• why do I need to add schema into URL field even if I have set parameter for schema properly in the settings of custom field?
• "mailto:" should not be visible to user in frontend
