Free Text Unlimited

Do you mean something like that: [wp24_domaincheck tld=”com”]?
And then the user would not have to type in the TLD because it’s defined in the shortcode?

Yes, that’s exactly the solution. “Allow to check all testable TLDs simultaneously.” Like the feature but it’s like identifying it with a shortcode.
In this way, for example, when querying TLDs specified with a shortcode on the home page. For the visitor who wants to make a detailed query, the “Free Text Unlimited (Type the TLD into domain name field, all available TLDs allowed)” feature can be activated on a different page.
Respect.

Thank you for the update. However, if “Free Text Unlimited (Type the TLD into domain name field, all available TLDs allowed)” is selected, the extensions specified in the shortcode are not taken into account. If no TLD is specified in the shortcode, then whatever option is selected in the settings should be the active feature (for example: “Free Text Unlimited (Type the TLD into domain name field, all available TLDs allowed)”).

If you use the shortcode more than once on a page, you would have to enable “Multiple use” in the advanced settings.

Usage example and setting are as follows;
Selection type: Free Text Unlimited (Type the TLD into domain name field, all available TLDs allowed)
Page 1: [wp24_domaincheck tlds=”com, net, org”]
(It’s asking me for TLDs. I think it shouldn’t, because the TLDs are already set.)
Page 2: [wp24_domaincheck]
(It asks me TLD.)

When using “Free Text Unlimited” and without typing a TLD only works when a single TLD is set in the shortcode.
I could change it, so that if TLDs a defined in the shortcode, the selection type internally switches to “Free Text Limited”. Then it would be possible to check all TLDs.

It’s integrated with the latest update.

Thank you for your update.
