```javascript
client
    .search('realestate-homes', { location: '1.20061.20512', ownership_type: 3, sort: 3 })
    .then(function(result) {
        var adId = result.entries[0].adId;
        return client.getAd(adId);
    })
    .then(function(ad) {
        console.log(ad.title, ad.links.alternate);
        ad.aData.general_text.forEach(function(e) {
            console.log(e.value.replace(/<br \/>/g, "\n"))
        });
    })

### Rendering Taxonomy Filters - Twig/Jinja2

Source: https://github.com/finn-no/lifestyle/blob/master/examples/nfinn/views/macros.html

This macro initiates the rendering of a hierarchical taxonomy filter by calling the 'taxonomyLevel' macro with the top-level children of the taxonomy definition. It's the entry point for displaying nested category structures.

```Twig
{% macro taxonomyFilter(filter) %}

{{ taxonomyLevel(filter.definition.taxonomy.children) }}

{% endmacro %}
```

--------------------------------

### Rendering Dynamic Filters - Twig/Jinja2

Source: https://github.com/finn-no/lifestyle/blob/master/examples/nfinn/views/macros.html

This macro acts as a dispatcher, rendering different filter types (range, select, or taxonomy) based on the 'f.type' property of the input filter object. It centralizes the logic for displaying various filter UIs.

```Twig
{% macro filter(f) %} {{ f.title }}

{% if f.type == 'range' %} {{ rangeFilter(f) }} {% elif (f.type == 'select') %} {{ selectFilter(f) }} {% else %} {{ taxonomyFilter(f) }} {% endif %}

### Rendering Taxonomy Level - Twig/Jinja2

Source: https://github.com/finn-no/lifestyle/blob/master/examples/nfinn/views/macros.html

This macro iterates through a collection of taxonomy children and renders each child using the 'taxonomyItem' macro. It's used to build out a single level of a hierarchical taxonomy display.

```Twig
{% macro taxonomyLevel(children) %}

{% for child in children %}1.  {{ taxonomyItem(child) }}
{% endfor %}

{% endmacro %}
```

--------------------------------

### Defining Title Block in Jinja2/Nunjucks

Source: https://github.com/finn-no/lifestyle/blob/master/examples/nfinn/views/search.html

```Jinja2
{% block title %}{{ title }}{% endblock %}
```

--------------------------------

### Rendering Select Filters - Twig/Jinja2

Source: https://github.com/finn-no/lifestyle/blob/master/examples/nfinn/views/macros.html

This macro iterates through the children of a select filter's taxonomy definition and renders each item's title. It's used for displaying a list of selectable options, often in a dropdown or checkbox group.

```Twig
{% macro selectFilter(filter) %}

{% for item in filter.definition.taxonomy.children %}1.   {{ item.title }}
{% endfor %}

{% endmacro %}
```

--------------------------------

### Closing Content Block in Jinja2/Nunjucks

Source: https://github.com/finn-no/lifestyle/blob/master/examples/nfinn/views/search.html

This snippet marks the end of the 'content' block, signifying that all content intended for this block has been defined. It's essential for proper template inheritance and structure.

```Jinja2
{% endblock %}
```

--------------------------------

### Rendering Individual Taxonomy Item - Twig/Jinja2

Source: https://github.com/finn-no/lifestyle/blob/master/examples/nfinn/views/macros.html

This macro renders an individual item within a taxonomy tree. If the item has children, it recursively calls 'taxonomyLevel' to display the nested structure; otherwise, it just displays the item's title.

```Twig
{% macro taxonomyItem(branch) %} {% if branch.children %} {{ branch.title }} {{ taxonomyLevel(branch.children) }} {% else %} {{ branch.title }} {% endif %} {% endmacro %}
```
