That simply means that your theme is not styling it. It should be there if you check the source. You will need to style it to look like the unordered list using css.

Please use the following code instead.

/**
 * Remove groups from user profile based on member type.
 */
function buddydev_remove_group_based_on_member_types() {
	if ( ! bp_is_user() ) {
		return;
	}

	$user_id = bp_displayed_user_id();

	if ( ! bp_has_member_type( $user_id, 'agent' ) ) {
		bp_core_remove_nav_item( 'groups' );

		$access = bp_core_can_edit_settings();
		$friends_link = bp_displayed_user_domain()? bp_displayed_user_domain() : bp_loggedin_user_domain();
		$friends_link = trailingslashit( $friends_link . bp_get_friends_slug() );
		bp_core_new_subnav_item(array(
			'name'            => __( 'Invitations', 'buddypress' ),
			'slug'            => 'invites',
			'parent_url'      => $friends_link,
			'parent_slug'     => bp_get_friends_slug(),
			'screen_function' => 'buddydev_groups_screen_group_invites',
			'user_has_access' => $access,
			'position'        => 30
		));
		// move the invitations to the friends screen.
	}
}

add_action( 'bp_setup_nav', 'buddydev_remove_group_based_on_member_types', 1001 );

/**
 * Helps us detect screen.
 */
function buddydev_groups_screen_group_invites() {
    add_action( 'groups_screen_group_invites', 'buddydev_load_invite_template' );
	groups_screen_group_invites();
}

/**

 */
function buddydev_load_invite_template() {
    add_action( 'bp_template_content', function () {
        bp_get_template_part('members/single/groups/invites');
    });

	bp_core_load_template('members/single/plugins' );
}

/**

 *
 * @param string $link original link.
 *

function buddydev_update_group_invite_link( $link ) {
    // for agent, do not break it.
    if ( bp_has_member_type( bp_loggedin_user_id(), 'agent' ) ) {

	$friends_url = bp_loggedin_user_domain() . bp_get_friends_slug() .'/invites/';
	$url         = trailingslashit( $friends_url . 'accept/' . $group->id );
	$url         = add_query_arg( array( 'redirect_to' => $friends_url  ), $url );

	//
	return wp_nonce_url( $url, 'groups_accept_invite' );
}

add_filter( 'bp_get_group_accept_invite_link', 'buddydev_update_group_invite_link' );

/**
 * Change the reject link url for the non 'agent' users.
 *
 * @param string $link original link.
 *
 * @return string
 */
function buddydev_update_group_reject_link( $link ) {
    // for agent, do not break it.
    if ( bp_has_member_type( bp_loggedin_user_id(), 'agent' ) ) {
       return $link;
    }

	$url         = add_query_arg( array( 'redirect_to' => $friends_url ), $url );

	return wp_nonce_url( $url, 'groups_reject_invite' ) ;
}

add_filter( 'bp_get_group_reject_invite_link', 'buddydev_update_group_reject_link' );

/**
 * Remove groups from adminbar based on member type.
 *
 * @param array $nav nav items.
 *
 * @return array
 */
function buddydev_filter_show_hide_groups_in_adminbar( $nav ) {
	if ( ! is_user_logged_in() ) {
		return $nav;
	}

	if ( ! bp_has_member_type( bp_loggedin_user_id(), 'agent' ) ) {
		$nav = array();
	}

	return $nav;
}

add_filter( 'bp_groups_admin_nav', 'buddydev_filter_show_hide_groups_in_adminbar' );

It will work if you try to accept from the Friends->Invites screen.

Problem:-
– I don’t see a way for filtering the link in the email notification.
– You also need code for filtering the link in the local notification(atleast 2 more filters).

Hi PresPhuture,
Thank you for posting.
Yes, it is possible to control which category/tags are shown

/**
 * Filter the BuddyBlog form settings and limit category/tag inclusion.
 *
 * @param array $settings settings array.
 *
 * @return array
 */
function buddydev_filter_buddyblog_form_settings( $settings ) {

	$tax                        = isset( $settings['tax'] ) ? $settings['tax'] : array();
	$tax['category']['include'] = array( 1, 2, 3 );// category ids to include.
	$tax['post_tag']['include'] = array( 5, 7, 9 );// tag ids to include.

	$settings['tax'] = $tax;

	return $settings;
}

add_filter( 'buddyblog_post_form_settings', 'buddydev_filter_buddyblog_form_settings' );

Please change the ids with your own. It will only list the category tags with those ids. I hope you can modify it form there on.

Hope that helps.

Hi Ekiz,
I see the problem. You are using ordered list while the code I posted allowed unordered list. I have updated the code to allow ordered list too now

/**
 * Add remove filters to allow more tags.
 */
function buddydev_add_remove_group_desc_filters() {
	remove_filter( 'groups_group_description_before_save', 'wp_filter_kses', 1 );
	add_filter( 'groups_group_description_before_save', 'bp_groups_filter_kses', 1 );
}

add_action( 'bp_loaded', 'buddydev_add_remove_group_desc_filters');

/**
 * Allow extra tags in group description.
 *
 * @param $tags
 *
 * @return mixed
 */
function buddydev_allow_extra_group_desc_tags( $tags ) {
    $tags['ul'] = array();
    $tags['ol'] = array();
    $tags['li'] = array();
    $tags['strong'] = array();
    $tags['b'] = array();
    return $tags;
}
add_filter( 'bp_groups_filter_kses', 'buddydev_allow_extra_group_desc_tags' );
