Developing A Realtor Theme For Hugo: Step 1 Building the pages

Introduction

I decided to develop a theme for realtors in my city as A LOT of realtors in my city are still using wordpress and I wanted to create an alternative for them.

The Plan

Here is the game plan:

Find an SSG that will work
Build out the pages first in HTML, SASS and JS
Build out the templates
Find a CMS that will work with the themes and SSG

For this article, I am going to cover the SSG and Pages

The SSG

For the static site generator, I decided to go with Hugo. It is simple to use and the templating engine is awesome! After reading the docs I think it will work with what I need.

Building out the pages

So, the main pages I require are:

Home
Listings
A listing
Staff Page
Contact Us

Home Page

Listings

For the listing page I will need to set up a filterable gallery.

The Gallery

I decided to go witht thise style of gallery I think it looks nice. Next to add some filtering

The filters

// File#: _3_advanced-filter
// Usage: codyhouse.co/license
(function() {
  // the AdvFilter object is used to handle: 
  // - number of results
  // - form reset
  // - filtering sections label (to show a preview of the option selected by the users)
  var AdvFilter = function(element) {
    this.element = element; 
    this.form = this.element.getElementsByClassName('js-adv-filter__form');
    this.resultsList = this.element.getElementsByClassName('js-adv-filter__gallery')[0];
    this.resultsCount = this.element.getElementsByClassName('js-adv-filter__results-count');
    initAdvFilter(this);
  };

  function initAdvFilter(filter) {
    if(filter.form.length > 0) {
      // reset form
      filter.form[0].addEventListener('reset', function(event){
        setTimeout(function(){
          resetFilters(filter);
          resetGallery(filter);
        });
      });
      // update section labels on form change
      filter.form[0].addEventListener('change', function(event){
        var section = event.target.closest('.js-adv-filter__item');
        if(section) resetSelection(filter, section);
        else if( Util.is(event.target, '.js-adv-filter__form') ) {
          // reset the entire form lables
          var sections = filter.form[0].getElementsByClassName('js-adv-filter__item');
          for(var i = 0; i < sections.length; i++) resetSelection(filter, sections[i]);
        }
      });
    }

    // reset results count
    if(filter.resultsCount.length > 0) {
      filter.resultsList.addEventListener('filter-selection-updated', function(event){
        updateResultsCount(filter);

    // check if there are custom form elemets - reset appearance

Tabs

I set up some tabs to host all of the main content for the listing. I think this will help separate everything and make it easier for the user to navigate.
