I'm able to increase width of Account name field from record view by modifying "custom\modules\Accounts\clients\base\views\record\record.php" and it is working fine
'name' => 'name',
'span' => 30, // added
'width' => '150%', // added
But it is not working while we are converting Lead to Account (Convert view)
I modified "custom\modules\Leads\clients\base\layouts\convert-main\convert-main.php" same as record.php but change not reflected Account name field width not increased.
Any help will be highly appreciable
