i want to have a fixed search button on mobile view as well even if i scroll down.

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

body .is-menu-wrapper {
    top: 30px;
    width: auto;
    position: fixed;
}
