i checked within a j!3.9

the following changes will solve. My experience in github, cloning, submitting and on is too little to do it in another way. Sorry for that.

Following is to be inserted

			<field
				name="show_street_address_headings"
				type="list"
				label="COM_CONTACT_FIELD_CONFIG_STREET_ADDRESS_LABEL"
				description="COM_CONTACT_FIELD_CONFIG_STREET_ADDRESS_DESC"
				useglobal="true"
				class="chzn-color"
				>
				<option value="0">JHIDE</option>
				<option value="1">JSHOW</option>
			</field>	

into following files at approx line number

254 \components\com_contact\views\category\tmpl\default.xml
302 \components\com_contact\views\categories\tmpl\default.xml
106 \components\com_contact\views\featured\tmpl\default.xml

			<field
				name="show_street_address_headings"
				type="radio"
				label="COM_CONTACT_FIELD_CONFIG_STREET_ADDRESS_LABEL"
				description="COM_CONTACT_FIELD_CONFIG_STREET_ADDRESS_DESC"
				default="0"
				class="btn-group btn-group-yesno"
				showon="show_headings:1"
				>
				<option value="1">JSHOW</option>
				<option value="0">JHIDE</option>
			</field>

into following file at approx line number

835 \administrator\components\com_contact\config.xml

This needs to be added to the database files in the insert of the extensions table

"show_street_address_headings":"1"

Somewhere.. forgivem as I am not too familiar with DB ins and outs

In the language file /public_html/administrator/language/en-GB/en-GB.com_contact.ini following constants need an entry:

COM_CONTACT_FIELD_CONFIG_STREET_ADDRESS_LABEL="Street Address"
COM_CONTACT_FIELD_CONFIG_STREET_ADDRESS_DESC="Show or hide a Street Address column in the list of Contacts."

This now allows the Street Address to be show or hidden in de contact category lists layout

$item->address

already is available to be used in templates

ie. in "core" /components/com_contact/views/category/tmpl/default_items.php insert at line 96

<?php if ($this->params->get('show_street_address_headings') && !empty($item->address)) : ?>
	<?php $location[] = $item->address; ?>
<?php endif; ?>

This tiny bit resolves the issue. Tested on a 3.9.18 and it works.
Surprising it was never there but it would be awesome if it could be added to current 3.9 and future 3.10 and 4.x

Just found out.. same applies to postcode / zip code field in contact list view

I was just looking in the new joomla 4 beta 1 and it seems ok.

Please let me know if I've misunderstood the issue, apologies if so.

I just checked 4.0 Beta. It is not in tab "list layout".

Hi @pieter-groeneweg sorry, I missed that it was in the list view, rather than the item view.
