Hi @Nikos Welcome to the community! Have you had a chance to browse our embed options here? There’s an option to add the form to your site as a popover or popup.  Depending on which plan you have, our advanced embed options would allow the form to appear automatically when the respondent lands on your site, and they can close it by clicking the ‘x’ button. 

@Nikos 

 but have the choice to dismiss it if they do not wish to complete it. 

it is really good to add a dismiss option on it its good for website user experience i also do same thing in my paintball guns site  

That's interesting @oral123! Can you tell us why this option would be useful to you? Oh and can you send us the link to your paintball funs website? Curious to check it out!
