It’s a year later but thought I’d post a solution – was trying to combine the wrong methods, and it’s actually a lot simpler than I’d thought. The issue was knowing how to insert the style select, but I didn’t how it was referred to in ACF arrays.
1) Find out the names of the toolbar elements for reference later on. In functions.php add the following:
add_filter( 'acf/fields/wysiwyg/toolbars' , 'my_toolbars' );
function my_toolbars( $toolbars )
{
echo '< pre >';
print_r($toolbars);
echo '< /pre >';
die;
}
2) Look at the bottom of the WP admin area and copy the array into a text file for future reference. We now know the names of the buttons.
< pre >Array
(
[Full] => Array
(
[1] => Array
(
[0] => formatselect
[1] => bold
[2] => italic
[3] => bullist
[4] => numlist
[5] => blockquote
[6] => alignleft
[7] => aligncenter
[8] => alignright
[9] => link
[10] => unlink
[12] => spellchecker
[14] => wp_adv
)
[2] => Array
(
[0] => styleselect
[1] => strikethrough
[2] => hr
[4] => removeformat
[5] => charmap
[6] => outdent
[7] => indent
[8] => undo
[9] => redo
)
[3] => Array
(

[4] => Array
(

)
[Basic] => Array
(
[1] => Array
(
[0] => bold
[1] => italic
[2] => underline
[3] => blockquote
[4] => strikethrough
[5] => bullist
[6] => numlist
[7] => alignleft
[8] => aligncenter
[9] => alignright
[10] => undo
[11] => redo
[12] => link
[13] => unlink
[14] => fullscreen
)
)
)
< /pre >
3) Remove or comment out the code above that displays the button array. Create your new custom toolbar.
add_filter( 'acf/fields/wysiwyg/toolbars' , 'custom_toolbars' );
function custom_toolbars( $toolbars )
{
// Add a new toolbar called "Custom" - only 1 row of buttons
$toolbars['Custom' ] = array();
$toolbars['Custom' ][1] = array('styleselect','bold','italic');
// return $toolbars
return $toolbars;
}
