Hi there @Sumit_2809, 

Welcome to the Community! 

Yes, you can definitely do this within an HTML template. The show/hide logic is just a user-friendly rendering of conditional If-Else statements in Django.

 
You can use this same logic to insert into your HTML template based on the content you would like to show or hide. To conditionally show content in your email, wrap this portion of the email an initial {% if insert_your_condition %} as well as the closing {% endif %} tag. You can reference the same profile/event variables you would use in the Display Options within Klaviyo's drag-and-drop editor.

 
I’d recommend checking out these helpful resources on conditional statements below to gain more insight!

It should be noted that since you’re using a custom HTML template, Klaviyo can’t assist with designing or building out this templates, however, I’d reach out to your developer or a Klaviyo partner to help build this out for you if you need assistance. 

Hope his helps!

Just to add to @Taylor Tarpley answer here, you can also use the Show/Hide feature for the Block or Section in the Drag and Drop version.  You can learn more about it here:
