remove preview ?

I hope you are well today, and thank you for your questions.

How can I remove the side preview like this here https://prnt.sc/YfGcgSgxPsJR ?

You can disable it in the search form AJAX options as displayed below.

And second question can you help me to create round corner (35px) in custom css please ?

You can achieve this by adding the below CSS code in the Custom CSS option of Ivory Search plugin settings on the path Admin Area -> Ivory Search -> Settings -> Settings

                                                                                                                    .is-form-style input.is-search-input {
    border-radius: 5px 0 0 5px;
}

.is-search-icon svg,                                     
span.is-search-icon {
    border-radius: 0 5px 5px 0;
}

Best regards,

You are always welcome here 🙂

Do you want to customize a border of AJAX search results or the search form?

Also, could you please share the page URL from your site where the search bar displays so I can help you to achieve it?

Ok
