{% macro tabs(tab_list, attrs = "") %}
{# Tab component
Parameters:
tab_list: list[tuple[str, str]] The list of tabs to display.
Each element of the list is a tuple which first element
is the title of the tab and the second element its content
attrs: str Additional attributes to put on the enclosing div
Example:
A basic usage would be as follow :
{{ tabs([("title 1", "content 1"), ("title 2", "content 2")]) }}
If you want to display more complex logic, you can define macros
and use those macros in parameters :
{{ tabs([("title", my_macro())]) }}
It's also possible to get and set the currently selected tab using Alpine.
Here, the title of the currently selected tab will be displayed.
Moreover, on page load, the tab will be opened on "tab 2".
<div x-data="{current_tab: 'tab 2'}">
<p x-text="current_tab"></p>
{{ tabs([("tab 1", "Hello"), ("tab 2", "World")], "x-model=current_tab") }}
</div>
If you want to have translated tab titles, you can enclose the macro call
in a with block :
{% with title=_("title"), content=_("Content") %}
{{ tabs([(tab1, content)]) }}
{% endwith %}
#}
<div
class="tabs shadow"
x-data="{selected: '{{ tab_list[0][0] }}'}"
x-modelable="selected"
{{ attrs }}
>
<div class="tab-headers">
{% for title, _ in tab_list %}
<button
class="tab-header clickable"
:class="{active: selected === '{{ title }}'}"
@click="selected = '{{ title }}'"
>
{{ title }}
</button>
{% endfor %}
</div>
<div class="tab-content">
{% for title, content in tab_list %}
<section x-show="selected === '{{ title }}'">
{{ content }}
</section>
{% endfor %}
</div>
</div>
{% endmacro %}
