Help resizing Search in Navigation Bar

I hope you are well today and thank you for your question.

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

.is-menu form label {
    width: calc( 100% - 100px );
}

.is-menu input.is-search-input {
    width: 100%;
}

Best regards,
Ivory Search Support

You are most welcome, I’m glad I was able to help you with this matter. There is no obligation but by your kind words I wonder if I could trouble you to leave a review based on this experience here:
