Here's a Javascript you can use to implement a dynamic search dropdown in Flare. Just save the script below in a file and include it in your Flare project, and then include the script in your template page, or any page where you want the dropdown to appear. You might need to adjust the CSS selector of the search input field based on your project's structure.
NOTE Updated 2024-05-20: Added a method to show the dropdown when the search input is focused.
class SearchManager {
constructor() {
this.debounce = this.debounce.bind(this);
this.handleSearch = this.handleSearch.bind(this);
this.displayResults = this.displayResults.bind(this);
this.clearResults = this.clearResults.bind(this);
this.showFullResults = this.showFullResults.bind(this);
this.hideDropDown = this.hideDropDown.bind(this);
this.showDropDown = this.showDropDown.bind(this); // Add this line
this.init();
}
debounce(func, delay) {
let debounceTimer;
return function () {
const context = this;
const args = arguments;
clearTimeout(debounceTimer);
debounceTimer = setTimeout(() => func.apply(context, args), delay);
};
}

const searchQuery = document.querySelector('.main-section .search-bar > input').value;
if (searchQuery.length > 0) {
MadCap.SearchHelper.SearchPane.Search(searchQuery, { searchContent: true }).then(this.displayResults);
} else {
this.clearResults();
}
