Repairing the collapsible side panel

I've successfully integrated the off-canvas sidebar template from Twitter Bootstrap into my project and have fixed it for small/medium views. However, I'm experiencing some difficulties when trying to make it work properly for extra-small devices.

Is there a way to ensure that it remains fixed as intended?

CSS

html,
body {
    max-width: 100%;
    overflow-x: hidden; /* Prevent scroll on narrow devices */
}
body {
    padding-top: 70px;
}

.sidebar-offcanvas {
    position: fixed;
    top: 50px;
    right: 0;
    height: 100%;
    width: 200px;
}
.sidebar-offcanvas, .sidebar-offcanvas a {
    background-color: #ECF0F1;
    border: none;
}
/*
 * Off Canvas
 * --------------------------------------------------
 */
@media screen and (max-width: 767px) {
    .row-offcanvas {
        position: relative;
        -webkit-transition: all .5s ease-out;
        -o-transition: all .5s ease-out;
        transition: all .5s ease-out;
    }

    .row-offcanvas-right {
        right: 0;
    }

    .row-offcanvas-left {
        left: 0;
    }

    .row-offcanvas-right .sidebar-offcanvas {
        right: -50%; /* 6 columns */
    }

    .row-offcanvas-left .sidebar-offcanvas {
        left: -50%; /* 6 columns */
    }

    .row-offcanvas-right.active {
        right: 50%; /* 6 columns */
    }

    .row-offcanvas-left.active {
        left: 50%; /* 6 columns */
    }

    .sidebar-offcanvas {
        position: fixed;
        top: 0;
        width: 50%;
    }
}

HTML

<div class="container">

    <div class="row row-offcanvas row-offcanvas-right">

        <div class="col-xs-12 col-sm-9 col-md-10">
            <my-notification></my-notification>
            <div ui-view></div>
        </div>

        <div class="sidebar-offcanvas" id="sidebar">
            <div class="list-group">
                .. omitted
            </div>
        </div>
    </div>
</div>

Answer №1

It appears that there may have been some confusion in your CSS code. The issue lies in the following snippet:

.row-offcanvas-right
.sidebar-offcanvas {
    right: -50%; /* 6 columns */
}

When combined with:

.sidebar-offcanvas {
    position: fixed;
    top: 0;
    width: 50%;
}

What this does is make the .sidebar-offcanvas element 50% wide, but then positions it to the right at a distance equal to 50% of its own width. This essentially pushes the element off the screen to the right, making it invisible. Depending on your desired outcome, you may need to adjust the right: -50%; to a different value, such as right: 0px;, to correct the positioning.

Answer №2

By default, when using .show on .offcanvas, the offcanvas will display with a header containing a close button and an optional body class for padding. It is recommended to always include offcanvas headers with dismiss actions or provide an explicit way to dismiss the offcanvas.
