Change categories block title in the left column to show parent category of selected category

[ksinghal]

Hi,

 

I have added categories block to the left column of my website. The title (i.e. heading) of this block always displays the name of currently selected category. I need to change this title to display the name of parent category of this selected category.

 

I have tried to look into 'blockcategories.tpl', but did not find any solution there.

 

I think there must be some tweak in 'hookLeftColumn' method of 'blockcategories.php', but could not understand the changes that need to be done there.

 

Need urgent help in this matter.

 

Note: I am using Prestashop 1.6 and default categories block.

 

Thanks in advance.
