How to set template parameters in menu items like "Multiple Categories", "My items" etc

You cannot set template parameter in category-like MENU items.

-- Some templates have almost no parameters and use only template positions, but blog template (it's category layout) relies heavily on template parameters in this case you have the following alternatives:

A.
If it is a category menu item then parameters defined in category configuration (category edit form) are inherited, but for menu items "My-Items" or "Multi-Categories" MENU items they just used default values. But there is a workaround though (see B below)

B.

1. Duplicate template 'blog' and create template 'blog-myitems' or 'blog-mcats' or 'blog-author' or 'blog-myitems2', etc , then edit files:
   components/com_flexicontent/templates/myblog1/category_items.php
   components/com_flexicontent/templates/myblog1/category_items_html5.php
2. And at the top of the file (just after first
   -- e.g. to define image use:
   

   $this->params->set('lead_use_image', 1);
   $this->params->set('lead_image', 'field15');
   $this->params->set('lead_width', 200);
   $this->params->set('lead_height', 150);
    
   $this->params->set('intro_use_image', 1);
   $this->params->set('intro_image', 'field15');
   $this->params->set('intro_width', 150);
   $this->params->set('intro_height', 120);

   
   -- e.g. to define leading number of items use:
   

   $this->params->set('lead_num', 4);
