this can be solved with https://docs.joomla.org/How_to_override_the_output_from_the_Joomla!_core

It seems that we can't override, I have tried chaneging order of fields in tempaltes/mytemplate/html/com_contact/contact/default_form.php

`<?php

defined('_JEXEC') or die;

JHtml::('behavior.keepalive');
JHtml::('behavior.formvalidator');

?>

		<?php $fields = $this->form->getFieldset($fieldset->name); ?>
		<?php if (count($fields)) : ?>
			<fieldset>
				<?php if (isset($fieldset->label) && ($legend = trim(JText::_($fieldset->label))) !== '') : ?>
					<legend><?php echo $legend; ?></legend>
				<?php endif; ?>
				<?php foreach ($fields as $field) : ?>
					<?php echo $field->renderField(); ?>
				<?php endforeach; ?>
			</fieldset>
		<?php endif; ?>

		<?php if ($fieldset->name === 'captcha' && !$this->captchaEnabled) : ?>
			<?php continue; ?>
		<?php endif; ?>

	<?php endforeach; ?>
	<div class="control-group">
		<div class="controls">
			<button class="btn btn-primary validate" type="submit"><?php echo JText::_('COM_CONTACT_CONTACT_SEND'); ?></button>
			<input type="hidden" name="option" value="com_contact" />
			<input type="hidden" name="task" value="contact.submit" />
			<input type="hidden" name="return" value="<?php echo $this->return_page; ?>" />
			<input type="hidden" name="id" value="<?php echo $this->contact->slug; ?>" />
			<?php echo JHtml::_('form.token'); ?>
		</div>
	</div>
</form>

Her is suggested that only way to archive this is hardcode custom field in override template
Your text to link here...

yes, maybe not the most easy/clean override, but the way to go

There is a problem with multilingual sites, you have to create 2 overrides

You can use this override to move captcha to bottom https://gist.github.com/SharkyKZ/592cc44c68eac9b3ef7e0b3abb2699f3.

If the function like now exists in Joomla! 4 for adding custom fields, it's should not be an override, but should be fixed in the Core of Joomla.

Absolutely agree with @svermassen @petrovicivan
This is a layout and UX bug.

@alikon
Please, re-open this issue.
Any chance to get a solution into J!4.2 ?

Thanks in advance.

This is definitely an issue that should be addressed.
There are easy ways to fix this. @SharkyKZ would you like to write a PR for it?
Note that I think the modifications should be done before the fields are loaded in the template file.

please test #38607 the code was there it was just wrong

Closing as having a pull request. Please test #38607 . Thanks in advance.

Nice work !!!

its only nice if it is accepted and for that it needs people to test it

For me it works.
But it's a YooTheme-site.
So I had to copy part of the code (changes) in the file from the template self.
So it's not the repro as it should be for the testing :-(

@petrovicivan can you take a look at #38607 and test the patch? Thank you!
