First of all thank you Brajesh for your help.
I tried your code i got all fields from xprofile, i want just to get all data saved from specific field called domaine (whish has list of activity like: architetural, science computer etc…)

This is the code :

 $profile_fields = array();

		$groups = bp_xprofile_get_groups(
			array(
				'hide_empty_groups' => true,
				'fetch_fields'      => true,
			)
		); ?>
		<select>
		<?php
		foreach ( $groups as $group ) {
			foreach ( $group->fields as $field ) {
				$profile_fields[ $field->id ] = $field->name; ?>
				<option><?php echo $field->name;; ?></option>
				<?php
				
			}
		} ?>
		</select>

I have xprofile COUNTRY FIELD wish has list like that : (USA, Canada, GBR) and i want to print all data in listbox.
this is exemple that i want:

`<select>
<option value=”USA”>USA</option>
<option value=”Canada”>Canada</option>
</select>`

Note: I fill COUNTRY FIELD FROM administration->users->profile_field->Country_field_name

Thank you so much Brajesh well done!
Now i want to get value selected and use it for filtring search like: select option Contry and select job of member with form search.

<?php
		$field_id = 94; // field 
		$field    = new  BP_XProfile_Field( $field_id );
		$options  = $field->get_children();
		echo "<select name='brajesh-Country'>";
		echo "<option value=''>Select country</option>";
		foreach ( $options as $option ) {
			echo '<option value="' . esc_attr( $option->name ) . '">' . esc_html( $option->name ) . '</option>';
		}

		echo '</select>';

		//Select City
		$field_id = 103;
		$field    = new  BP_XProfile_Field( $field_id );
		$options  = $field->get_children();
		echo "<select name='brajesh-city'>";
                echo "<option value=''>Select Job name</option>";
		foreach ( $options as $option ) {
			echo '<option value="' . esc_attr( $option->name ) . '">' . esc_html( $option->name ) . '</option>';
		}

		echo '</select>'; 
		
		?>
            <div class="row">

		<div id="brajesh-search-company" class="col-sm-12 col-md-12 col-lg-12">
			<div id="members-dir-search-company" class="dir-search" role="search">
				<?php bp_directory_members_search_form(brajesh_custom_ids( 'company_name_field' 
                 )); ?>
			</div><!-- #members-dir-search -->
		</div>
			
	  </div>

<?php
function brajesh_custom_ids( $field_name, $field_value = '' ) {
  
  if ( empty( $field_name ) )
    return '';
  
  global $wpdb;
  
  $field_id = xprofile_get_field_id_from_name( $field_name ); 
 
  if ( !empty( $field_id ) ) 
    $query = "SELECT user_id FROM " . $wpdb->prefix . "bp_xprofile_data WHERE field_id = " . $field_id;
  else
   return '';
  
  if ( $field_value != '' ) 
    $query .= " AND value LIKE '%" . $field_value . "%'";
      
    // $query .= " AND value = '" . $field_value . "'"; 
      
	$custom_ids = $wpdb->get_col( $query );
  
  if ( !empty( $custom_ids ) ) {
    // convert the array to a csv string
    $custom_ids_str = 'include=' . implode(",", $custom_ids);
    return $custom_ids_str;
  }
  else
   return '';  
}
?>

Thank you again
