It is given in transposh FAQ's : http://transposh.org/faq/

here's what I would suggest :

1. Use the WPLMS Child theme or the blank child theme.
2. Copy the header.php file from the parent WPLMS theme into the child theme.
3. Make modifications in the header.php file in the child theme as follows :

a. locate line <div class="col-md-8 col-sm-9"> in header.php and change it to

PHP Code:

 

<div class="col-md-8 col-sm-9">
<?php if(function_exists("transposh_widget")) { transposh_widget(); }?>
<?php .... //original code is shifted down

 

b. Save.

4. Activate the child theme, it should have the transposh widget in the headertop area.
